Everyone is aware that quotes in strings used in SQL cause all sorts of problems. As developers, it is our duty to ensure that an end user never sees an SQL error because we didn’t handle his input appropriately!
But how the heck do you ensure that quotes are handled correctly? The following function will take a string and return it enclosed with quotes and all instances of quotes in the string will be doubled up.
For example if I call QuotedString(“This is a “string” example”) then it will return:
“This is ““a string”” example”
Public Function QuotedString( _ strText As String) As String Const conQuoteChar = """" QuotedString = conQuoteChar _ & Replace$(strText, conQuoteChar, conQuoteChar & conQuoteChar) _ & conQuoteChar End Function
NOTE: you should always check for specific methods designed to escape strings in whatever framework you are using. I had to roll my own because Microsoft Access.
